Be it known that I, EARL V. SANDERS, a' citizen of the -United States, 'residinga't.

- Pawnee, in the county of Sangamon and.

State of Illinois, have invented new and useful Improvementsin Pneumatic Cush-- ioningl Devices for vehicles, oi which the My. invention relates to pneumatic; eush; lOHHlg. devices for vehicles and refers more particularly to that class 'OfdViCBS' designed used on automobiles.

as substitutes for the pneumatic time new] The object of my invention to provide, A,

a device in which the-cushioningand shock, absorbing qualities of'fthe; ordinary pneumati'c tire' maybe retainemandl'the wear on the cushioning means be reduced to a minif A further object is fto arran geimy cushion:- ing means ina position where it will be; easily accessible for'refi-lling with air or for Y mum by removing thatfimeanslfrom direct contact'with the groundgi's repairs, and at thellogical position toreceive the shock and jar to'thebest advantage.

I my invention comprises arearrangement o elements and a novelconstructio'n of parts which will be hereinafter fully described,-

From the foregoing descr pt on, it will be readily seen that. my. invention provides improved means for cushioningthe jar-in vehicles, and that, by a rearrangement'of 4 old elements, I- have provided a substitute mechanism for j the pneumatic tire asordi narilyemployed,- which will eliminate the.

wear on 'such'a cushioning means by the removal' of that means from dlrect c0ntactwith the ground. While I have trated.-"a preferred embodiment of my invention, I do not wish to be restricted thereto, except for such restrictions as the claims herein described and illus- 1 which'body may be 'attached'byany well a ne b sitioned to support the main body of a Ve- I hide, vertical guide pins carried by said axle and adapted to receive said housing, bufier may import, as .it is obvious that slight changes in the relation and construction may head on said guide pins adapted to limit upward and downward movement of the housing, vertically perforated slide means on'the housing whereby said housing may move upward and downward on the guide pins carried by said axle, cushioning means positioned between the slide means on the housing and the buffer heads on the guide pins, substantially asdescribed.
